Warrants [Abstract] |
Warrants | Note 11 – Warrants During the year ended December 31, 2011, warrants to purchase 1,974,774 shares of common stock were granted to the Management Firm at an exercise price of $0.01 per share. These warrants have a term of 7 years and vest immediately. Fair value of $2,153,442 was calculated using the Black-Scholes option-pricing model. Variables used in the Black-Scholes option-pricing model include (1) discount rate ranging from 1.92% to 3.17%, (2) warrant life of 10 years, (3) expected volatility ranging from 64.77% to 70.72%, and (4) zero expected dividends. The management firm receives warrants equal to ten (10%) percent of the issued and outstanding capital stock of the Company on a fully-diluted basis on the effective date of the agreement. The warrants are subject to weighted average non-dilution provisions to be calculated on the basis of the post-money fully diluted capitalization of the Company upon closing of any transaction, financing or otherwise, up to and including the Public Company transaction, provided that such anti-dilution provisions shall not extend beyond the date of any exercise of the warrants by the management firm prior to the closing of the Public Company transaction. Since these warrants vest immediately, the Company recorded the entire fair value of $2,153,442 as stock-based compensation expense during the year on these warrants issued by the Company.
